HEATER.

Specification of Letters Patent. Pa'tntedJ 8' 19 Application filed July 15, 71918. Serial No. 244,979.

To all whom it may concern:

Be it known that we, IsAAo C. Porrnn and CHARLESH. BAYER, citizens of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful improvements in Heaters, of which the follow-' ing is a specification.

Our invention relates to an improvement in heaters, and the object is to provide a sheet-metal stove or heater of the so-called Perfection type that is adapted for burning a solidified chemical fuel.

Anotherobject is to do away with smoke and the generation of gases and odors, and to provide a heater and burner in which this solidified chemical fuel may be burned and V the heat therefrom increased or diminished,

and in other words absolutely under control of the operator.

WVith these and other possible objects in view, our invention consists in a heater preferably made in sections and having air inlets and outlets at the bottom and top, a can for the fuel, a chimney, and means for controllingthe draft through the chimney whereby the intensity of the heat is absolutely controllable and the light capable ofbeing easily extinguished.

This invention further consists in constructional details which will be hereinafter described and pointed out in the claims.

In the accompanying drawings:

Figure 1 is a vertical sectional view through the heater, showing all the parts assembled and in place;

Fig. 2 is a view in side elevation of the fuel can and chimney;

Fig. 3 is a View of the chimney alone;

Fig. 1 is a view of the two forms of bands used for controlling the air inletsandoutlets' Fig. 5 is a view of the baffle-plate or hood at the top of the chimney.

The heater is preferably made of sheetiron and in two sections hinged together, as shown in Fig. 1. These sections, for conthe venience, will be designated the base section 1 and the top section 2. The base section is provided with a number of air inlet holes 3, both in the sides and bottom, and this base section is generally mounted on legs 4 to hold it above the floor and allow free cir culation of air in through holes 3 to oxygen to support combustion. The top secthe escape of the crimped inwardly as shown at 7, or other wise constructed as found most suitable for the purposes The numeral 8 indicates what we term the chimney. This is, in the main, cylindrical in form with an enlarged lower end with an outwardly-curved flange 9 to fit snugly. over the crimpedupper edge 7 of the fuelcan.

The length of the chimney is such that it reaches from the top'of the fuel can, where its lower end rests, to a point nearly at the top of the heater, where it is provided with a baflie-plate or hood 10 to deflect the heat rising through the chimn'ey,causing its eX- pulsion downwardly and outwardly in 0on tact with the side of the heater, whereby to greatly increase the radiation and intensity of the heat. V

In order to regulate the combustion throughthe chimney, two rows of holes are provided, one set 11 in the lower end of the chimney, and the other 12 at its upper end within the area of the baffle-plate or hood.

The lower set of holes 11 is for the, ingress of air from the base of the heater to support combustion, and the upper set 12 for the escape of the products of combustion beneath and into the area of the baflle-plate or hood, when itis deflected and disseminated throughout the upperarea of the heater.

The size of the openings 11 and 12 may be controlled in any approved manner, as it is through this medium thatthe combustion is regulated and controllech As a simple means for doing this, the bands 13 and 14 are provided. These bands encircle the chimney snugly and are provided with openings 15 and 16 respectively, which c0rrespond-with the holes or openings 11 and 12 in the chimney,and are adapted to open if orrics.

drawings.

; The chimney is secured rigidly in the top vsection 2 of the stove or'heater, and the fuel-can 6 may rest loosely on the bottom of the base section, where itis held firmly in place and centered by the chimney when the topis closed and in its normal position as shown in Fig. 1.

By means of this heater, we are enabled to overcome the ob ect1on to the use of ordinary coal o1l or kerosene which requlres an expensive burner, and which, under the most favorable conditions, is liable to smoke more or less. At the same time, we are able to obtain as much, if notmore, intense heat, while the heater is absolutelyodorless.

The fuel is molded in the can where it 'may be stored and confined almost indelinitely by keeping'the can closed air-tight, so that when the heater is to be used it is simply necessary to open a can of the fuel 7 and place it in the base section, whereupon after touching a match to the open upper end of the can and'igniting the fuel (which 7 ignites instantaneously) the top is closed,

and it remains to adjust the damper-bands to regulate the amount of heat that is desired; i

It is obviousthat more or less slight changes vmight be resorted to in the form and. arrangements of the several parts described without departure from the spirit and scope ofour invention; and hence we do not any means wish to be limited to 7 set forth,

2. A heater-made in two sections, a can Y to contain fuel located in the base section,

the top section having a chimney rigidly secured thereto, the lower edge of which fits down upon and holds the can oftfuel in 5 place in the base section when-the top section is in its normal position,bothsections having perforations for the circulation of air and products of combustion, the chim ney also perforated, and means for opening 6 and closing and regulating the size of said chimney perforations. 3. A heater made in two sections, ac'an to contain fuel located in the base'section, the top section having 'a chimney rigidly 6 secured thereto, the lower edge of which fits down upon and holds the can of fuel in place in the base section when the top section is in its normal position, both sections having perforations for the circulation of air and products of combustion, the chimney also perforated, means for opening and closing and regulating the size of said chimney perforations, and a baffle-plate or hood over the upper end of the chimney for deflecting the heat rising throughthelatter.

v In testimony whereof we afliX our signatures. V ISAAC C. POPPER CHARLES H. BAYER.
